Melbourne, July 05: The secret behind Will Smith`s loving marriage and box-office success has now been revealed and it has nothing to do with his looks, instead it’s “lots of sex.”

“Lots of sex,” a news daily quoted him, as telling FoxNews.com.

"All the time, every day. Just lots of sex keeps me goin` good,” he added.

But Will admits that he wasn`t totally swept off his feet when he started dating wife Jada Pinkett Smith in the mid-90s.

"I was very interested that first night, but I was in a bizarre mental space," he said.

"Three months into it we were at her mom`s house and it just hit me. I looked at her and just knew this was it,” he added.
